Can't enter bios after transferring PC to a new case with new GPU

toymachinary · Feb 28, 2017

I recently purchased a GTX 1070 and then realized it was too big for my case. I took apart my PC and reinstalled it in a new case with the GTX 1070 plugged in. When I power on - the monitor shows my motherboard's (gigabyte z77 ds3h) main screen but when I hit "delete" it does not enter bios. I get no response from F9 or F12 either. When I hit "ctrl alt delete" the screen goes black for a moment so it appears the keyboard is functioning. I am pretty certain all the cables are plugged in correctly and I have checked that they are snug. The one difference I can think of is my HDs might be plugged into different SATA ports but I wasn't sure that would make any difference (plus I am pretty sure I plugged them into the same ones). I would really appreciate any suggestions!

first off, they have to be in the correct sata ports as listed in the motherboard's manual.

then try resetting the CMOS battery with the power supply disconnected (obviously)

Thanks for the response!

I should clarify I am using the same SATA ports but I have 4 HDs and they might not all be plugged into the same port as they were before in the old case, although I am pretty sure they are. I took the battery out for about 20 mins then put it back in and rebooted but the same thing happened.

I am going to try to boot up with my old graphics card when I get home from work today and see if it's any different.

If you know which HD windows is on try only plugging that one in to be sure its not the rebuild that has damaged the HD itself.

So it turns out my hard drive with my OS on it was wiped. I unplugged my GPU and plugged the monitor directly into the motherboard and booted Windows and re-installed from a USB. Now I can get on when not using my new GPU but I have the same problem when I plug it back in.

I have seen similar threads and a lot of people advise to update the bios. I have version F2 and there is an F9. Should I try this? Is it risky at all?

I updated the bios and it works fine now.
